Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component testing, in particular to a photovoltaic component rupture testing machine. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules, which are composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. They have the characteristics of long service life and strong mechanical compressive force. The purpose of the module crack test is to test the impact resistance of photovoltaic modules and the impact resistance of photovoltaic modules and module frames. The test process is achieved through a photovoltaic module crack tester. Photovoltaic modules will be subject to various impacts when working outdoors, which may cause damage to the photovoltaic panels in severe cases. Therefore, photovoltaic modules need to be cracked before leaving the factory.

[0003] After searching, it was found that a photovoltaic module rupture testing machine was disclosed in China's public utility model patent publication number CN219736763U. A limit strip is provided on the rotating arm, and the air pipe on the pneumatic release assembly can be clamped into the clamping groove of the limit strip to prevent the air pipe from interfering with the wire rope, thereby extending the service life of the air pipe and also avoiding affecting the impact force when the impact ball moves downward, thereby ensuring the accuracy of the rupture test. However, when the above-mentioned rupture testing machine is used for testing, the photovoltaic module is directly exposed for testing, without any fragmentation protection, and cannot block the debris generated during the test, so that the debris can easily hit the tester and cause injury to the tester. Therefore, a rupture testing machine that can protect the tester during the test is needed. Utility Model Content
